Utopia- Thomas More

In Utopia, More paints a vision of the customs and practices of a distant island. Advocating instead a world in which there is religious tolerance, provision for the aged, and state ownership of land, Utopia has been variously claimed as a Catholic tract or an argument for communism and it still invites each generation to make its own interpretation.
